May 16, 2019 - Microsoft recently announced that it will enable third-party applications and use OAuth 2.0 to provide users with greater security. This change is confined to 3PIP certified Skype for Business IP phones and requires the update of Microsoft server synchronization for all 3PIP partners. Yealink released new firmware for its complete range of Skype for Business phones in Mid-May, well in advance of the  **January 15, 2020** deadline for Microsoft’s global service update. In order to ensure that end users can successfully sign in to the phones in question, administrators must complete the following steps before the deadline. **Step One** Admins will be asked to consent one time on behalf of the organization to grant the application the necessary permissions. a) URL access: [https://login.microsoftonline.com/common/adminconsent?client_id=f1faadeb-88b3-4852-8138-3b9e23b24619](https://login.microsoftonline.com/common/adminconsent?client_id=f1faadeb-88b3-4852-8138-3b9e23b24619) b) Sign-in using the tenant admin account rather than as a user. Please note that only administrator accounts can grant the relevant permissions. Non-administrator account users will be forwarded to the Need Admin Approval Page. c) When successful, the Device Login Page will recognize the device as a  **Yealink – Skype for Business Certified Phone.** d) Click  **Accept **to grant all the required permissions on the below consent screen from Azure. Then, other users in the organization can sign-in according to the typical Web Sign-in and there will be no need to re-grant any permissions. **Step Two** Upgrade the firmware to the version that bundles the third-party application ID.
